For the purpose of this standard, washer-dryer combinations, when operated as a dryer, are considered as a tumble dryer. NOTE 101 For washing function, see IEC 60704-2-4. This

40、 standard is also applicable for gas-fired electric tumble dryers. 1.1.2 Types of noise Replacement: The methods specified in ISO 3743-1, ISO 3743-2 and ISO 3744 can be used for measuring noise emitted by tumble dryers. 1.1.3 Size of the source Replacement: The method specified in ISO 3744 is applic

41、able to noise sources of any size. When applying ISO 3743-1 and ISO 3743-2, care should be taken that the maximum size of the appliance under test fulfils the requirements specified in 1.3 of ISO 3743-1 and ISO 3743-2. 1.2 Object Addition: Requirements for the declaration of noise emission values ar
